Business 40 Improvement Project

As Winston-Salem's downtown continues to be a thriving urban hub, the 1.2-mile stretch of Business 40 that runs through downtown is underway for structural improvements and overall beautification. The three-year project, spearheaded by the North Carolina Department of Transportation (NCDOT), is a multi-phased project is slated for completion Spring 2020. The finished project will offer travelers safer roadways in and out of Winston-Salem's bustling downtown, and add and improve pedestrian walkways through and around downtown.

Latest News:

  • Beginning Sunday, July 7 at 9 p.m., the outside lane of eastbound and westbound Business 40 will be closed between Cloverdale Avenue and Peters Creek Parkway. This closure will reduce Business 40 traffic, at this location, to one lane in each direction for approximately 90 days.

    Initially, the outside lane in each direction will be closed and then at some time during the middle of the 90-day closure, the outside lanes will be opened and the inside lanes will be closed. The scheduled completion date for this work is October 5, 2019.

    With the westbound direction of Business 40 being reduced to one lane beginning at Peters Creek Parkway, crews will also reduce the ramp from Peters Creek Parkway to westbound Business 40 to one lane.  Consequently, one of the left turn lanes from Peters Creek Parkway will be closed in front of BB&T Ballpark.

    During this closure time, crews will work to lower the elevation of the new Business 40, between Fourth Street and Peters Creek Parkway, creating a smoother transition when all of Business 40 is opened in Spring 2020.
  • Liberty Street bridge is now open!
  • As of August 1, Business 40 construction crews are closing the intersection of High Street and Brookstown Avenue in downtown Winston-Salem, extending the Brookstown Avenue closure to include the Brookstown Avenue / High Street intersection. With High Street being a one-way traffic pattern, closing the intersection prevents access to the parking lot of the Shaffner House/Flour Box Tea Room and Cafe. To provide access, the portion of High Street between Marshall Street and the parking lot has been temporarily changed to a two-way pattern.  Motorists traveling north on Marshall Street can turn left onto High Street and access the parking lot.
